Welcome to Steemit @sumitbro! :c)
Your story has touched me - humbleness emits from every sentence and the pride that you do harbour is sincere.
You say that you have learnt a fair bit about a number of fields but not completely so. You mention your past struggles with the English language but your writing seems to have come in leaps and bounds since then.
I sincerely look forward to seeing what you post about on this medium. I'll level with you however - this is not a get rich quick platform. It will require a degree of dedication to penetrate - and the first step is to wark on your 'personal branding'.
This won't necessarily require you to change anything about what you present yourself as - but it might change the way that you do so. Its the stuff that gives you identity - uniqueness - that stand-out factor. Good luck!
Since you're new here, a quick read through this post may prove helpful.
Thanks @pathforger
